What internal pressure (in the absence of an external pressure ) can be sustainerd by (a) a glass tube of wall thickness and rediuas `sigmma )(b)` breacking stress of glass `=5xx10^(7)`Pa.
[Hint: outward force due to internal pressure is balanced by the inward elastic foprce .]

A glass container encloses gas at a pressure 4 xx10^5 Pa and 300 K temperature. The container walls can bear a maximum pressure of 8 xx10^(5) Pa. If the temperature of container is gradually increased find temperature at which container will break.

A glass container encloses gas at a pressure 4 xx10^5 Pa and 300 K temperature. The container walls can bear a maximum pressure of 8 xx10^(5) Pa. If the temperature of container is gradually increased find temperature at which container will break.

A glass capillary tube of inner diameter 0.28 mm is lowered verically into water in a vessel. The pressure to be applied on the water in the capillary tube so that water level in the tube is same as that in the vessel is lambda xx 10^(5) N//m^(2) . Then find lambda in nearest integer (surface tension of water = 0.07 N//m and atmospheric pressure = 10^(5)N//m^(2) ) :

The internal energy of an ideal gas is given by U = 1.5 PV. It expands from 10 cm^(3) to 20 cm^(3) against a constant pressure of 2 xx 10^(5) Pa. heat absorbed by the gas in the process is

A glass container encloses a gas a pressure of 8 xx 10^(5) pa and 300 K temperature. The container walls can bear a maximum pressure of 10^(6) Pa. If the temperature of container is gradually increased, find the temperature at which the container will break.
